Letters Patent No. 96,938, dated Normnber 16, 1869.

IMPROVEMENT IN CORN-SHELLERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all persons to whom these presents shall come:

Be it known that I, WILL AM M. MAYALL, of Gray, in the county of Cumberland, and State of Maine, have invented certain new and useful Improvements in Oorn-Shellers; and that the following is a full and complete description of the same, reference being bad to the accompanying plate of drawings, forming a part thereof.

My invention consists- First, in arranging, with the shelling-jaws, a series of wheels, whereby the operation of shelling is increased, the friction decreased, and the feeding improved. I

Secondly,in a novel construction of'clamp, by means of which thesheller can be secured to the edge of a table, or other horizontal plane, or to the side of a tub, or other vertical plane, as may be desired.

Thirdly, in the combination and arrangement of various parts, as will be hereafter set forth.

In the accompanying plate of drawings, my improvements in corn-shellers are illustrated- Figure 1 being an elevation from one side;

Figures 2 and 3, end elevations;

Figure 4, a longitudinal vertical section, taken inthe plane of the line a; x, fig.,3;

Figure 5, detail sectional view, in the plane of the line y y, fig. 1; and

Figure 6, detail sectional view in the plane of the line z z, fig. 1.

A, in the drawings, represents an upright or post, in the upper end of which is hung, by its centre shaft, B, a large bevel-gear wheel, 0.

D, handle secured to gear-wheel O, for convenience -in turning it.

E, bevel-gear wheel, hung in a two-part circular strap, F.

One part, G, of this strap F, is of one and tho I same piece of metal as the upright A, and the other,

same.

The shelling-faces P are concave from end to end, and are arranged opposite to each other, being acted upon by spiral springs Q, placed over the guide-rods 0, between the jaws N and the flange L. Y

R, wheels, arranged in the shelling-jaws, and, by their edges, projecting into the space between the jaws.

By means of these wheels the action of the shelling-jaws is facilitated, their friction decreased, and their tendency to draw or feed through the ear of corn much increased and improved, and with less expenditure of power.

S, a vertical frame, secured by strap T, with screws, U, to upright or post A. V, two rolls, concave in shape, from end to cud,

These rolls are hung, one above the other, in the frame S, between its side upright, \V, in which they have bearings, and are arranged, by means of sliding boxes. X, and spiral springs Y, to be susceptible of opening from or closing upon each other.

These rollers, when in positioniupon the upright A, extend across the open gear-wheel E, and are located upon the opposite end of such gear to that having the shelling-blades, as plainly shown in the drawings. Z, pinion-wheel, on main gear-wheel shaft B, and A pinion-wheel, gearing into said pinion Z. G shaft of pinion-wheel A", carrying another pinion-wheel, 1), arranged to on gage with a pinion-wheel, E, onthe shaft, to one of the rolls V.

By means of this gearing, such,1'oll, with its mate, is turned.

The lower end, F, of post A, is turned off, to adapt it to receive a clamp, for clamping the machine toa suitable place.

The clamp A, under the present invention, is made with a slit 01; opening, G", by which it can be set over and upon the edge ofa. table or tub, where, by means of a thumb-screw, H", it can be secured.

1 and J two holes in clamp A, in planes at right angles, or near] y so, to each other.

By these holes the clamp can be set on the turnedoff end of the post A, according as it is desired to bring the slit G of the clamp, into a horizontal or vertical position, for fixing the machine to a table or tub, &c.

L set-screw, provided for the receiving-holes of the clamp A, into which the post A is set.

In shelling corn by my improved -n'1achinc, iirstplace the car, by one end, in the jaws N, when, turn- I ing the gear-wheel C, such jaws are carried around the ear, removing the kernels therefrom, and passing the car through the hollow gear-wheel E to and between the rolls V, by means of which it is not only held from turning, thus leaving the hand of the person free, but to a greater or lesser extent drawn through the jaws.

The rim or flange L acts as a shield to thc shellhwjaws, preventing the kernels from being spread or thrown out and scattered about, as they are removed by the shelling-jaws.

Having thus described my improvements, I shall state my' claims, as follows:

1. The wheels R, to the shelling-jaws, pose specified. 2. The clamp for the purholes I and J substantially as described, for the purpose set forth.

A, constructed with slit G, and- 3. The combination and arrangement of the flange L, shellers N, rollers R, guide-rods O, springs Q, rolls V, springs Y, and gear-wheels O E, substantially as herein represented and desgribed.
